Semantic relations in English determine how meaning is constructed and how lexical items relate to each other within a specific context. Analyze the following statements:
I.Hyponymy is a relationship of inclusion, where the meaning of a more specific term (the hyponym) is included within the meaning of a more general term (the hypernym).
II.Antonymy always involves absolute opposites, meaning that words like "hot" and "cold" cannot be placed on a scale or modified by adverbs of degree in formal registers.
III.Polysemy refers to a single lexical item that possesses multiple related meanings, often originating from the same etymological root or metaphorical extension.
Which of the statements above is/are CORRECT?
